Question

好吧所以我的问题是我有一个用于显示googlemaps的iframe

iframe的src将设置为点击googlemaps，其中从数据库中读取的地址作为位置插入

当时帧只是纯白色，甚至没有图片出现，但是如果将src路径放入浏览器URL中它工作正常，我的测试网址是 “http://maps.google.com/maps/api/staticmap?markers=27+Landseer+Street,+Belfast&size=500x300&sensor=false”

这是有效的，因为你会看到你是否放入地址栏。

我的目标是让三个框架全部单独命名，然后在它们上面设置src。这是我到目前为止的代码

    Session("recentAddressmap3") = ""
    Session("src1") = ""
    Session("src2") = ""
    Session("src3") = ""
    Dim recentCount As Integer
    recentCount = 0
    Dim addresstest As String = "27 Landseer Street"
    Dim words As String() = addresstest.Split(New Char() {" "c})

    ' Use For Each loop over words and display them
    Dim word As String
    Dim newaddress As String = ""
    Dim loopcounter As Integer = 0
    For Each word In words
        If loopcounter = 0 Then
            newaddress = word
            loopcounter = loopcounter + 1
        Else
            newaddress = newaddress & "+" & word
        End If
    Next
    '''''''''''''''''''''''''''''''''''''''''' DO ENTRY RECENT 1 '''''''''''''''''''''''''''''''''''''''''''''''''''
    Session("recentAddressmap1") = newaddress & ",Belfast"
    Session("src1") = "http://maps.google.com/maps/api/staticmap?markers=" & Session("recentAddressmap1") & "&size=500x300&sensor=false"
    'MsgBox(Session("src1"))
    visualAddress1.Attributes.Add("src", Session("src1"))
End Sub

Answer 1

如何给iframe提供一个ID + runat = server，然后从VB设置src？
